The U.S. Department of Justice arrested Gannon Ken Van Dyke, a soldier who participated in the January operation to capture Venezuelan President Nicolas Maduro, on Thursday for allegedly using confidential information to profit from prediction market bets. The case marks the first major federal insider trading prosecution tied to a decentralized event market.
Soldier Placed $33,000 in Polymarket Bets Hours Before Operation
According to DOJ filings, Van Dyke wagered over $33,000 on Polymarket predicting the timing and outcome of the Maduro capture and the detention of his wife Cilia Flores. He withdrew more than $400,000 in winnings and attempted to delete his account. U.S. Attorney Jay Clayton for the Southern District of New York said Van Dyke “allegedly violated the trust placed in him by the United States Government by using classified information about a sensitive military operation to place bets on the timing and outcome of that very operation, all to turn a profit.”
Charges Include Three Commodity Exchange Act Violations, Up to 60 Years
Van Dyke faces three counts of violating the Commodity Exchange Act, one count of wire fraud, and one count of unlawful monetary transactions. The total maximum sentence is 60 years. The case highlights a legal grey area: Polymarket allows betting without mandatory KYC, making it difficult to prevent insider trading.
Polymarket Cooperated, Says 'System Works'
Polymarket stated it identified the user and referred the matter to the DOJ, adding: “Insider trading has no place on Polymarket. Today’s arrest is proof the system works.” In March, the platform updated its rules to explicitly ban trading by those who have non-public information and can influence outcomes. However, enforcement remains weak due to the platform's decentralized roots and lack of mandatory identity verification.
Controversy Over War Bets Continues
Polymarket has faced scrutiny for allowing bets on war-related events, including a now-removed market on a nuclear bomb detonation by the end of the year. Rep. Seth Moulton (D-Mass.) called the rescue-bet market “disgusting” and alleged that Donald Trump was an investor with potential access to non-public intelligence. The Van Dyke arrest may push regulators to take a harder stance on prediction market oversight.
